I'm torn between several choices, but here are each of my opinions.
Salty- I love salty snacks, they taste great!
Sweet- Yum. But too much makes my teeth sensitive.
Sour- When combined with sweet, I love it! On its own...I still love it!
Spicy-I like spicy snacks and food. But too much spicy food...and my mouth is in flames. :O
I prefer spicy food and snacks, but salty is a close second. I wouldn't choose sour it makes my tounge have some kind of painful jerking reflex, spicy does that to but not as bad.
Sweet-I love sweet food but not too sweet.
Salty-I don't like salty food much never been my favorite
Spicey-I love spicey food I prefer it over sweet food any day allot of people think I'm weird because of that lol
Sweet and salty. I love how they taste.. I really don't care for spicy stuff, but there's a few things that I like. And then for sour...*shivers* I can't stand sour. >_<
I suppose salty if I can only pick one. But I often like to alternate between sweet and salty snacks.
Spicy and sour are flavors I tend to prefer at meals, not as snacks. If I eat a snack with those flavors, I get confused as to whether I've had a meal or not.
